The Lullaby

The Lullaby was a song created by Sorae Igarashi for Shiro. It is transmitted by the Mother Goose System to keep the Wretched Egg's powers under control. The song is about a woodpecker, a hint to Sorae's son Ganta Igarashi, nicknamed Woodpecker. Sorae always cried when playing the song, as she says that this is "Shiro's Song", and by the time Sorae writes this song, she has begun to feel remorse for all the pain she put Shiro through.
